COKE- OVEN.

SPECIFICATION forming part of Letters Patent No. 289,887, dated December 11, 1883,

Application filed June 13, 1883. (No model.)

To aZZ whom it may concern:

Be it known that I, J OSEPH BUTLER, a citizen of the United States of America, residing at Kennon, in the county of Belmont and State of Ohio, -have invented certain new and useful Improvementsin Coke-Ovens, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to coke-ovens, the object being to provide an oven of improved construction, whereby an effective draft will be insured to aid combustion and to discharge the sulphur and gases arising from the coal.

The invention consists in the combination, with an oven and its main discharge flue or stack, of draftpassages arranged in the sides of the oven and adapted to admit air to the interior of the oven, and escape-passages for conveying the products of combustion to discharge-fines arranged independently of the The invention further consists in the features of construction and combinations of parts hereinafter fully described, and pointedout in the claims.

In the drawings, Figure 1 is a side elevation of my improved oven, with parts shown in dotted lines. Fig. 2 is a transverse vertical section of the same. Fig. 3 is a longitudinal vertical section, and Fig. 4 is an end elevation of the oven.

A represents the oven proper, formed with a feed-opening, a, for coal, and the usual semielliptical top. The side walls, B B, and front end wall, 0, are preferably of brick-work, and near the upper edge of each side wall, B, is formed a longitudinal passage, D, extending the entire length of the oven, and communicating at the forward end of the latter with escapeflues F F by means of curved connecting-flues G G. These curved flues G G are arranged within a space, E, formed by a partition, H, arranged parallel to the end wall,

0, of the oven. The partition H is formed with an opening, h, through which the products of combustion pass to the main flue or stack I, arranged centrally between the fines F F. The inner sides of the walls B B are formed with a series of openings, J and J, to admit the products of combustion to the 1ongitudinal passages D D. Adjacent to the rear end of the oven, and preferably just forward of the rear openings, J, each of the longitudinal passages D is closed. by afilling or block, j, of noncombustible material. passagesD D are open at their rear ends, as shown in Fig. 4, to admit air to theoven to support combustion. Each of the dischargeflues F F and I is provided with a suitable damper, i.

From the construction and arrangement of flues thus described, it will be apparent that the air will enter the rear open ends of the passages D D, and pass through the openings J to the interior of the oven. Vhen the fluesF F are closed by their dampers, the gases and other products of combustion will be discharged through the main flue I. It will be understood that the coal in the oven rests below the openings J and J of the passages D D. After the oven has been started sufficiently, the main flue I is closed, thus compelling the escape of the gases through the passages D D and their escape-fines F F.

In Figs. 1 and 4 I have represented vertical guideways L L, secured to the inner sides of the rear ends of the sides B B of the oven. Between these guideways L L is arranged a vertically-sliding gate, M, secured at its upper. end to a chain, N, which passes over a pulley, O, mounted upon a shaft, 0, supported in bearings or standards P P, secured to the oven. The chain N is provided with a coun terbalance-weight, a.

The sliding gate M consists of a metallic frame, R, and a filling or body portion, S, of brick-work. The gate as thus constructed is well adapted to resist the heat of the oven, and is therefore much more durable than the ordinary metallic door or gate, and the devices for sliding the gate admit of the ready opening and closing-of the oven.

WVhat I claim as new is- 1. In a coke-oven, the combination, with side walls, each formed with a longitudinal passage or flue communicating with the interior of the oven by a series of openings, as described, of escape-flues communicating with said longitudinal passages, and arranged independently of the main flue or stack of the oven, substantially as set forth.

2. In a coke-oven, the combinatiomwith the Said p longitudinal passages formed in the side walls material, of a partition, H, having an escapeof the oven, and provided with openings J opening, the main discharge-flue, the'esoapeand J, of blocks or fillings for closing said pasfines F F, and connecting-fines G G, substan- 1 5 sages, escape-flues communicating with said tially as set forth.

5 passages, and a main discharge-flue, each of Intestiinony whereof I affix my signature, in said fiues being provided with a damper, subpresence of two witnesses, this 9th day of June,

stantially as set forth. 1883.

3. In a coke-oven the combination with the longitudinal passages formed in the side walls Y JOSEPH BUTLER 0 of the oven, and provided with a series of open- Vitnesses:

ings, as described, and closed near their rear G. \V. MCGUIRE,

ends by blocks or fillings of noncombustible H. C. BARTOW.
